So Inverse Tangent is :tan-1 (Opposite / Adjacent) = θExample: Find the size of angle x° tan x° = Opposite / Adjacent tan x° = 300/400 = 0.75 x° = tan-1 (0.75) = 36.9° (correct to 1 decimal place)Other NamesSometimes sin-1 is called asin or arcsin Likewise cos-1 is...
In this chapter, we discuss the inverse cosine and inverse tangent functions, and their application to the solution of the basic equations cosx=Aand tanx=A. As we mentioned, in order to construct the inverse function, we need to select a monotonic interval with the maximum length in the ...

Sine, cosine, and tangent are the three fundamental trigonometric functions intrigonometry. To find the value of these trigonometric functions, we simply get the ratio of the two sides of aright triangle. SOHCAHTOA is a mnemonic used to remember the formula of these three trigonometric functions...
Cosine rule, in trigonometry, is used to find the sides and angles of a triangle. Cosine rule is also called law of cosine. This law says c^2 = a^2 + b^2 − 2ab cos(C). Learn to prove the rule with examples at BYJU’S.
